uEnv.txt missing, nfs-uEnv.txt found instead

Hi,

Any idea what happened with the uEnv.txt file and why it seems to be called different?

Also, it is safe to add:

##Disable HDMI
  optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN


to the nfs-uEnv.txt file to disable HDMI virtual cape at boot?
